Is Panting at Night a Reason to be Concerned for Older Dogs?

Panting in dogs is completely normal. Dogs do it to regulate their body temperature when they are hot or exhausted after exercising. But excessive panting at night when they are not particularly active is a cause for suspicion. An old dog panting at night could be potentially suffering from a serious medical condition. Moreover, the lack of restful sleep due to excessive panting in older dogs can also have other negative consequences on their health. So let’s find out why your dog is panting at night and how to help!

Top 6 Reasons Older Dogs Pant at Night

So why do dogs pant at night? There are many possible reasons. While some of these are natural or hereditary, many can mean serious trouble for your dog’s health. The top reasons include:

1. Heatstroke

Extremely hot weather can cause heatstroke in dogs and can be one possible reason for your old dog’s panting. Keep your dog away from the sun during the day and well-hydrated to prevent heatstroke.

How to diagnose: A dog suffering from heatstroke will pant abnormally, have red gums, body temperature over 104, increased heart rate, and abnormal thirst. As seriousness increases, dogs can be wobbly, have glazed eyes, or even start having seizures.

Is it serious: Heatstroke can be quite serious and cause life-threatening problems like swelling of the brain, kidney failure, and intestinal bleeding. It’s thought that up to 3 in 10 dogs suffering from heatstroke will die.  

How to treat: If you think your old dog is suffering from heatstroke, move them to a cooler part of the house, pour some cool (but not cold) water over them, and give them ice cubes to lick. A fan can be a great help in cooling them down once you’ve wet their fur. If they are showing any more serious signs, you should arrange to take them to a veterinary clinic immediately.

2. Respiratory issues

A senior dog panting at night could be suffering from respiratory distress. It could be pneumonia or other pulmonary diseases. If you notice abnormal panting at night, it’s always best to visit your veterinarian for an accurate diagnosis.

How to diagnose: Aside from panting, you might notice coughing, difficulty breathing, and lethargy if your dog has respiratory issues.

Is it serious: Respiratory issues are serious and can worsen if not treated quickly.

How to treat: If your dog’s panting could be related to respiratory problems, they need to see a veterinarian.

3. Cushing’s disease

Cushing’s disease is an adrenal disease in which a dog’s adrenal glands produce too much cortisol – a stress hormone. Your dog could be panting at night due to Cushing’s disease.

How to diagnose: Symptoms of Cushing’s disease include excessive panting and shaking, increased thirst, increased urination, hair loss, and a potbelly.

Is it serious: Cushing’s disease has no cure, unfortunately, but the symptoms can be managed.

How to treat: Cushing’s will continue to worsen without medication. You’ll need to take your dog to the vet for blood tests in order to get a diagnosis and regularly check that the medication is working as expected.

4. Pain

Pain could also be a reason for your dog’s panting at night. This is especially likely if they are restless and grumpy.

How to diagnose: Agitation, growling, hiding, shallow breathing, and an increased heart rate are all signs of pain in dogs. However, some dogs won’t show any signs of pain other than panting more.

Is it serious: The seriousness of your dog’s condition in such a case will depend on the root cause of the pain.

How to treat: Once your vet has worked out why your dog is in pain, they can prescribe suitable pain relief. Do not use OTC pain relief for dogs – not only are many toxic to dogs, but senior dogs are more prone to underlying conditions that can make these treatments more dangerous. For instance, liver changes are common in senior dogs, and these can make Tylenol a dangerous choice. Learn how to manage pain in older dogs or read our article “Is my senior dog in pain?”.

5. Heart disease

Cardiovascular disease can also be the reason behind your senior dog panting at night. Old dogs are at greater risk of heart disease, and it can affect all breeds.

How to diagnose: Symptoms of heart disease in dogs include dry coughing, shortness of breath, restlessness, rapid weight loss, and fatigue. Your veterinarian will need to listen to your dog’s heart and may recommend an echocardiogram (ultrasound) or an x-ray to help determine the exact problem.

Is it serious: Although heart disease is serious, many treatment options are available to increase the quality of life.

How to treat: Contact your vet for a detailed diagnosis and treatment plan. Make sure you keep up with all recommended medications – gaps in treatment due to forgotten pills can cause relapses. Avoid high-salt foods and strenuous exercise, and do your best to make your longtime canine companion comfortable. Learn more about heart disease in older dogs.

6. Stress and anxiety

Stress can manifest as panting in dogs and must be appropriately managed. An old dog panting and pacing at night can be suffering from anxiety.

How to diagnose: A dog panting due to anxiety will also pace, bark, shiver, hide, or destroy furniture. You might spot other behavioral changes if your dog is stressed.

Is it serious: Stress and anxiety in dogs are quite common but should be carefully managed and treated to protect your dog’s quality of life.

How to treat: So how to stop a dog’s panting from anxiety? Calm an anxious dog through massage, gentle petting, and physical exercise. Use mental and physical stimulation, consistent routines, and supplementation to reduce stress. You may need to talk to your veterinarian about prescription medication or to a behaviorist for further advice. Learn more about senior dog anxiety and natural remedies to help with anxiety.

Three Tips to Help a Senior Dog Panting at Night

If you’re still wondering how to calm your panting dog, the following tips can help.

1. Create a calming environment

Reduce stress and anxiety by consciously creating a calming environment. Senior dogs’ needs change as they get older, and you must adjust accordingly to keep them as comfortable and relaxed as possible. If your senior dog is the anxious type, be sure to give them a safe space to retreat to when anxious or stressed.

2. Make sure your dog isn’t hot

Dogs normally pant to cool down. If your dog is panting at night, make sure they are not too hot and move their bed to a cooler location. You can further reduce the risk of heatstroke by giving your old dog an ice cube with their favorite treat inside, a damp towel to lay on, and access to cool water.

3. Regular exercise

Regular exercise is an excellent way to reduce panting due to stress, anxiety, and pent-up frustration. Take your old friend on long walks, increase their playtime, and get them more dog toys to give them an outlet for all that extra energy. Take extra care to provide sufficient mental stimulation in addition to physical workouts. You can offer this stimulation by letting him sniff and explore on walks, getting some puzzle toys, or teaching him new tricks. Read our article about exercising older dogs safely.

Final words

While panting is perfectly normal when a dog is hot or exhausted, excessive panting at night when they are not active can be a cause for concern. If they are sleeping in the hotter part of your house, move them to a cooler place and give them cool water to drink. However, if that doesn’t seem to be the reason, they might have an underlying medical condition. Take them to the vet for an accurate diagnosis and start the treatment immediately.
